    At last our Nordic Summer Nights are coming to an end, and many
    satellites can be seen after 2300 local time (when this summer's
    excessive rain clouds disperse)
    
    On Aug.04 at 20:34:51.7 while looking for EarlyBird rk near
    zeta Cep in ENE 64 deg el I found a mag +4.0 satellite
    descending. During 30 seconds or so, it faded to +7.
    Direction, speed, position, and time within 0.2 s fits:
    NOSS 7 (D)
    1 16623U 86014D   00210.08340257  .00000100  00000-0  11623-3 0    09
    2 16623  63.4112 246.6301 0392000   4.2162 355.7838 13.40341013    07
    
    I also observed USA 144 on the right place and within 1 sec or less,
    Minotaur Rk 26066 slowly tumbling +4/+8, which caused me to lose it,
    and Terra Centaur 25995 steady.
    Unknowns identified as #14819, #11683, #10861, #17974, #22284.
    
    One unknown disappeared 21:28:01 behind trees W of Bootes but at mag. +2.
    Local direction of motion (230 deg) implies a 105 deg incl. or so,
    but SeeSat 1 was predicted at 21:18
    
    22:27 to 22:33 UTC I observed Iridium 24. The brightest
    flashes were not impressive, but possibly well-defined enough to
    enable determination of flashing axis and surfaces, if a few more
    observations like this, in other siderial directions, are obtained.
    Please post/let me know!
    The three positions below show low positional accuracy, because I
    obtained them from predictions for the observed flash times.
    
    I failed to see USA 116, but I note that Russell (+Ted+...?) observed it.
